New blog just dropped. https://techcommunity.microsoft.com/t5/security-compliance-and-identity/a-new-modern-and-secure-print-experience-from-windows/ba-p/4002645 We are making massive changes to the Print System in Windows to improve security. This represents a pretty big leap forward for security in Windows. The Print System in Windows has historically been a key target for attackers and these changes make significant reductions in total attack surface.
More over, we intend for this to become the default for users in the future. No more loading 3rd party print drivers, no more high privilege services, and robust exploit mitigations enabled to protect users.
There is a lot of work to do, this first release is only a step in the direction we are taking. But I feel it is the right direction for user safety.
